Catheters, Urinary, Ureteral, Ablation
Definition : Ureteral catheters designed for endoscopic incision (ablation) of strictures in the proximal and distal ureter and at the ureteropelvic junction. These catheters typically consist of a 10 Fr tube with radioopaque markers that includes a balloon near its distal tip to define the area of stenosis, and a monopolar electrocautery cutting wire with a small active surface (typically 2.8 cm length); the procedure is usually performed under fluoroscopic guidance. Ablation ureteral catheters are used for the treatment of ureteral obstructions (endoureterotomy) and ureteropelvic junction obstructions (endopyelotomy).
